The H.264/264 video format was developed to provide good quality video at a lower bitrate level. The format has a large range of applications that attempt to cover video solutions from Internet streaming applications through to HDTV broadcasting with near lossless coding.

H.264/264 contains a number of features that allow it to compress video more effectively than previously. The main advantage of H.264 is the compression rate which is about twice as effective as MPEG-4. The image quality is a lot better and as such playback is more fluent, added to this the lower bit rate for network transmission means that it is widely adopted.

MPG is commonly associated with video and audio compressions MPEG-1 or MPEG-2. This is designed to compress audio and video to formats that can be downloaded. Movies with this extension are of lower sizes and greater quality, but quality differs from original VCR videos. This file format can run on Mac, Windows and other portable devices.

MPEG-1 is a standard for lossy compression of video and audio. It is designed to compress VHS-quality RAW digital video and CD audio down to 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) possible. Today, MPEG-1 has become the most widely compatible lossy audio/video format in the world, and is used in a large number of products and technologies. Perhaps the best-known part of the MPEG-1 standard is the MP3 audio format it introduced.
